Substitute Values into an Equation and Solve for a Variable

Narrator: A bus traveled for 3.1 hours at a constant speed of 62 miles per hour. Use the formula distance equals rate times time to find the total distance the bus traveled in miles. Round your answer to the nearest tenth. So we’re going to start with our formula, we that distance is equal to rate times time and then we’re going to plug in what we know. We know that the bus was traveling for 3.1 hours ok so we're going to put 3.1 for time and the speed, the rate was 62 miles per hour so we’re going 62 here. And we have those multiplied by each other. Ok and now it’s asking us to find the total distance and we know that our distance is equal to our rate times time so we can multiply 62 times 3.1 to find our distance. So we plug that into our calculator 62 times 3.1 gives us 192.2. So we know that that’s 192.2 and we didn’t really use the units right now as far as miles per hour or hours because we are going to cover those later in another section but since we know that they’re talking about miles in the problem we know that our distance is going to be in miles. So this is 192.2 miles.
